<h4 class="subsection">9.39.2 SCORE Assembler Directives</h4>

<a name="index-directives-for-SCORE"></a>
<a name="index-SCORE-directives"></a>
<p>A number of assembler directives are available for SCORE.  The
following table is far from complete.
</p>
<dl compact="compact">
<dt><code>.set nwarn</code></dt>
<dd><p>Let the assembler not to generate warnings if the source machine
language instructions happen data dependency.
</p>
</dd>
<dt><code>.set fixdd</code></dt>
<dd><p>Let the assembler to insert bubbles (32 bit nop instruction /
16 bit nop! Instruction) if the source machine language instructions
happen data dependency.
</p>
</dd>
<dt><code>.set nofixdd</code></dt>
<dd><p>Let the assembler to generate warnings if the source machine
language instructions happen data dependency. (Default)
</p>
</dd>
<dt><code>.set r1</code></dt>
<dd><p>Let the assembler not to generate warnings if the source program
uses r1. allow user to use r1
</p>
</dd>
<dt><code>set nor1</code></dt>
<dd><p>Let the assembler to generate warnings if the source program uses
r1. (Default)
</p>
</dd>
<dt><code>.sdata</code></dt>
<dd><p>Tell the assembler to add subsequent data into the sdata section
</p>
</dd>
<dt><code>.rdata</code></dt>
<dd><p>Tell the assembler to add subsequent data into the rdata section
</p>
</dd>
<dt><code>.frame &quot;frame-register&quot;, &quot;offset&quot;, &quot;return-pc-register&quot;</code></dt>
<dd><p>Describe a stack frame. &quot;frame-register&quot; is the frame register,
&quot;offset&quot; is the distance from the frame register to the virtual
frame pointer, &quot;return-pc-register&quot; is the return program register.
You must use &quot;.ent&quot; before &quot;.frame&quot; and only one &quot;.frame&quot; can be
used per &quot;.ent&quot;.
</p>
</dd>
<dt><code>.mask &quot;bitmask&quot;, &quot;frameoffset&quot;</code></dt>
<dd><p>Indicate which of the integer registers are saved in the current
function&rsquo;s stack frame, this is for the debugger to explain the
frame chain.
</p>
</dd>
<dt><code>.ent &quot;proc-name&quot;</code></dt>
<dd><p>Set the beginning of the procedure &quot;proc_name&quot;. Use this directive
when you want to generate information for the debugger.
</p>
</dd>
<dt><code>.end proc-name</code></dt>
<dd><p>Set the end of a procedure. Use this directive to generate information
for the debugger.
</p>
</dd>
<dt><code>.bss</code></dt>
<dd><p>Switch the destination of following statements into the bss section,
which is used for data that is uninitialized anywhere.
</p>
</dd>
